SELF-INKING HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 420,967, dated February11, 1890. Application filed November 24, 1888- Serial No. 291,769. (Nomodel.)

To all whom it may concern.-

Be it known that we, WILLARD W. SAWYER and WVILLIAM A. FORCE, both ofthe city, county, and State of New York, have invented an ImprovedSelf-Inking Hand-Stamp, of which the following is a specification.

The object of our invention is to provide a hand-stamp on whichimpressions can be quickly and uniformly made, and in which thetype-plate or printing-block can be quickly removed and replaced byanother.

The invention consists in the details of improvement and thecombinations of parts that will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 is a plan view of our improvedhand-stamp, showing the type-plate in the printing position, and Fig. 2is a vertical longitudinal section of the same on the line 0 c, Fig. 1,showing the type-plate resting against the inking-pad, being the normalposition of the parts.

In the accompanying drawings, the letter A represents the base or standof our improved hand-stamp, and a is carried by the base, upon which thepaper to be printed is placed.

B B are standards or uprights supported by the base A, which standardscarry the operating parts of our hand-stamp.

D is a rock-shaft that is journaled in the standards B and extendsacross the base A, as shown in Fig. 1. To the shaft D are secured theends of a forked handle E. The handle E preferably embraces thestandards B B, as shown in Fig. 1.

F is a stamp-head or type-supporting plate that is carried by the armsof the handle IE, it being pivoted to said handle, as at b, so that itmay turn or swing freely on its pivots. To the stamp-head F we attach atype-plate or printing-block G. (See Fig. 2.)

The type-plate G may consist of a block of wood or other material uponwhich rubber or other type H are secured, or the type and plate G may bein one piece or otherwise variously arranged. The type-plate G isremovably carried by the stamp-head F,- and a bed or platen.

that are adapted to receive the pins e, so that when the type-plate G isplaced against the stamp-head F and the pins 6 passed into the aperturesf the type-plate will be held In proper position on the stamp-head; butthe pins 6 may project downward from the plate G into the holes in thelugs cl. The typeplate G is also provided with a handle or the like gnear its upper end for convenience of insertion and withdrawal.

I is an inking-pad that is carried in a vertical or nearly verticalposition by the standards B. The pad I may be of any of the well-knownconstructions adapted to retain ink to be transferred to the type II.The inking-pad I we prefer to make removable and reversible, and forthis purpose we provide the standards B each with a vertical groove h,into which the ends of the pad I may pass, as clearly shown in Fig. 1.The pad I is provided on opposite sides with handles or the like i, forconvenience of removal, reversal, (to. As shown in Fig. 2, the verticalpad I is at right angles to the horizontal platen a. The type-plate G isheld against the pad I by the action of a spring .I, which is coiled forthis purpose around the rockshaft D, the ends of which spring contact alug or bar j, carried by the standards B, the middle portion of saidspring being passed over a screw or stud Z on the shaft D. The tendencyof the spring J is to turn the shaft D in the direction of the arrow inFig. 2, and thus to swing the handle E toward the pad I, and therebypress the type against the pad, as shown.

In order to make an impression upon the paper on the platen a, thetype-plate G must be swung from the vertical position shown by fulllines in Fig. 2 to the horizontal position shown by dotted lines in saidfigure. To

accomplish this we attach to the stamp-head F pins or rods L, thatproject at about right angles to the face of the stamp-head z. e.,forwardly when the stamp-head is vertical.

lines in Fig. 1.

These pins or rods L pass freely through swiveled studs M, that arecarried by the standards B above the platen a, as shown in Fig. 2. Asthe handle E is swung down toward the platen a, it will carry thestamphead F with it and move it, with the typeplate, away from the padI. As the stamphead E is thus moved, the pins L will slide in theswiveled studs M for a certain distance, and as the pivots l) of thestamp-head F begin to descend the pins L will cause the studs M to turn,and these in turn, being held by the stationary standards B, will swingthe stamp-head I from the vertical position to the horizontal position.The continued depression of the handle E will 110w bring the type intocontact with the platen a or paper laid upon it, producing animpression. As the stamp-head descends, the pins L will slide in thestuds M. The printing position is clearly shown in dotted lines in Fig.2, also in full hen pressure on the handle is released, the spring Jwill turn the shaft 1) in direction of the arrow, Fig. 2, therebycarrying the handle E, the type-plate and stamp-head away from theplaten a and pressing the type against the pad I. As the stamp-head F isthus moved, the pins L will slide in the studs M, thereby causing themto turn as the pivots I) return through their are, which brings thestamp-head back into the normal position.

By placing the pad I above the platen a and at right angles to said bed,or nearly so, the type do not require much movement from the bed, andthe pad I and type are readily removable and within convenient reach tobe replaced or changed.

The swivelcd studs M, instead of being perforated, may be solid, ifstraddled by forked or slotted pins L.

N is a suitable gage against which paper to be printed is placed.

Having now described our invention, what We claim is-- 1. Thecombination of the base A and its platen a with the inking-pad I,carried at about right angles to said platen, the face of the pad Ibeing perpendicular to the face of the platen a. and of the type-plateG, stamphead F, pins L, carried thereby, swiveled studs M, through whichthe pins L pass, and handle E, to which the stamp-head is pivoted,substantially as specified.

2. The combination of the base A, platen a, standards B, and handle E,with the stamphead F, pivotally carried by said handle and having thepins L, that extend at right angles to the face of the stamp-head, andwith the swiveled studs M, receiving said pins, substantially asdescribed.

The combination of the base A, standards l3, shaft D, torsional springJ, for turning said shaft, handle E, carried by said shaft, stamp-headF, pivotally carried by said handle, pins L on said stamp-head andextendin g at a right angle to the face of the stamp-head, swiveledstuds M on the standards l3, and inking-pad I, all arranged for opth eeration substantially as herein shown and described.
